There are two ways to dynamically instantiate an object from its type:
Call Activator.CreateInstance method
Call Invoke on a ConstructorInfo object obtained from a Type
Activator.CreateInstance accepts a Type and optional arguments that get passed to the constructor:
using System;
using System.Reflection;
using System.Collections.Generic;
class MainClass
{
static void Main()
{
int i = (int)Activator.CreateInstance(typeof(int));
DateTime dt = (DateTime)Activator.CreateInstance(typeof(DateTime),2000, 1, 1);
}
}
